An uplink transmission method and device, a computer readable storage medium and a terminal. Said method comprises: when an uplink process is started, starting a corresponding timer; and when the timing duration of the timer has reached a preset timing duration and the uplink process is still unsuccessful, terminating the uplink process and triggering other processes. Said method is able to be used for uplink transmission when the LBT fails multiple times. Furthermore, triggering other processes while terminating the uplink process is able to shorten the duration of the uplink process, avoiding the increase of the delay of the uplink process.
